Reports: Lance Armstrong Has Told Livestrong Staff He's Sorry

Cycling superstar Lance Armstrong, who has been stripped of his many victories because anti-doping authorities say he used performance enhancing drugs throughout his career, has reportedly told the staff at his Livestrong cancer charity that he's sorry. But it's not clear at this hour exactly what it is he's supposedly apologized for.

"Armstrong addressed the staff Monday and said, 'I'm sorry.' [A person with knowledge of what happened] said the disgraced cyclist choked up and several employees cried during the session. The person also said Armstrong apologized for letting the staff down and putting Livestrong at risk but he did not make a direct confession to the group about using banned drugs. He said he would try to restore the foundation's reputation."

ABC News says Armstrong "apologized today to the Livestrong staff ahead of his interview with Oprah Winfrey, a foundation official [said]. The official did not provide details."

That interview with Oprah, which is being taped at Armstrong's Austin home today, is due to air on her cable network Thursday at 9 p.m. ET and will be webcast on Oprah.com. We expect there will be many leaks about what he says before it's broadcast.

But in the past two weeks, both The New York Times and USA Today have reported that Armstrong has discussed publicly adding that he cheated during career. And then he agreed to the interview with Oprah — who can provide a high-profile platform for a public admission.
